Automata Theory is a branch of computer science that deals with designing
abstract selfpropelled computing devices that follow a predetermined sequence
of operations automatically. An automaton with a finite number of states is
called a Finite Automaton. This is a
brief and concise Learn Automata Theory that introduces the fundamental
concepts of Finite Automata, Regular Languages, and Pushdown Automata before
moving onto Turing machines and Decidability.

The Learn Automata Theory has been prepared for students pursuing
a degree in any information technology or computer science related field. It
attempts to help students grasp the essential concepts involved in automata
theory.

The Learn Automata Theory has a good balance between theory and
mathematical rigor. The readers are expected to have a basic understanding of
discrete mathematical structures.
